Noddles Front Brake Upgrade

[Noddle]

Hi,

I've been wanting to do this for ages , I special ordered these blank rotors from DBA and they have been sitting in my spare room for a few years now.

and now I have some time, the weathers getting nice ( no shed to work in though ), and I found a small engineering firm,

the spacers between the hub and rotors, the enlargement of the center hole for the rotor, and the caliper spacers, all came to $50, not to bad I thought.

I did a little more last night,

made my first flare ( brake line flare ), what a mess that was, so off to youtube to see how it was done,

now I'm a expert.

Hi,

Another beautiful day, so good weather to finish my brake upgrade.

Originally I left the 3/4 Master cylinder on, Brake worked fine, soft pedal, but a lot of travel, probably 3/4 way to the floor,

So I went to put a 7/8 master cylinder on, of course this would not fit the brake booster, the 4 bolts have a different spacing.

So I compared this to my part part '73 four door, different brake booster ( my 4 door was a little larger than what's on the 2 door),

So I swap this out from the 4 door, fitted the 7/8 master cylinder, brakes work really good, pedal still soft, but only travels about a inch or so,

So, can someone tell me , which is the original brake booster for a '73 model, from these pictures ?

Not sure if it matters, but the 4 door has the 250mm rotors, and the 2 door has the 270 mm rotors

Would it be different between 73 and 74? I have a 74 and can check when at the car next for you

I don't know, but my other 2 (1977) have a larger brake booster again.

Theory of combos for S30 but it matches Nigel's empirical observations above:

Sorry for the later reply,

Calipers are Toyota S13WB ( 4 runner from memory, each caliper had, 4 x 45mm pistons )

Rotors, were special order DBA425USL & DBA425USR ( they did not have the stud holes drilled / blank )

They are actually from a '91 Toyota Surf, ( found my ebay bid )

The slot for the   rotot looks to small  ( this maybe for a solid rotor )
